A terrifying species of spider that once plagued the northeastern US is making a return, and the new infestation is spreading deeper into the country than ever before. The bright yellow Joro Spider, which originated in Japan, China, Korea, Taiwan, and other parts of Asia, has seen its population spike since they last plagued the US in 2024. Experts cautioned that these venomous arachnids are poised to spread across the US thanks to a process called ballooning, where they form ‘sail-like trails of silk that lift them off the ground.’ Female Joro spiders have a bright yellow body with blue strips and red markings, making them hard to miss. Males can be spotted by their more brownish color and smaller size. The females also build large, golden webs to capture their prey, and these are increasingly common as the population swells. How do spiders migrate across the globe ?
